and was rather difficult to figure when I was getting to my stop prior to 
having Loadstone.  But now I have a check point file that is named for the 
gym and has 3 check point in it.  The corner near my house, the shopping 
plaza in between that we may stop at and have breakfast  and the stop near 
the gym.  I show check points only and have no major reason to know exactly 
where I am on a normal basis.

But last Saturday the bus broke down just before the shopping plaza and we 
would have another half mile to go to get to the gym.  I didn't know exactly 
where the bus broke down, but we got off because the driver said it would be 
some time before a replacement would be there.  I called the gym to tell our 
trainer that we would be late and she asked where we were.  I unchecked the 
selection to use check points only and told her where we were and she said 
to wait there and she came and got us.

It's situations like this that I've found Loadstone to be a valuable piece 
of technology, but wouldn't shell out over $1000 for the other GPS 
solutions.
